reactivity series

Question 1

Most metals react with acid

Answer 1

acid + metal → salt + hydrogen (can see bubbles of H2 given off)

Question 2

Almost all metals react with oxygen

Answer 2

metal + oxygen → metal oxide
○ Only metal that does not react with any of the above is gold, because it is
extremely unreactive

Question 3

displacement reactions

Answer 3

You can see if one metal is more reactive than another by using displacement
reactions:
o Easily seen when a salt of the less reactive metal is in the solution
▪ More reactive metal gradually disappears as it forms a solution
▪ Less reactive metal coats the surface of the more reactive metal

Question 4

reacts with water

Answer 4

Potassium
Sodium
Lithium
Calcium

Question 5

reacts with dilute acid

Answer 5

Potassium
Sodium
Lithium
Calcium
Magnesium
Aluminium
Carbon
Zinc
Iron

Question 6

conditions in which iron rusts

Answer 6

Both air and water are necessary for iron to rust – i.e. oxidation – gain of oxygen
results in corrosion

Question 7

oxidation

Answer 7

gain of oxygen OR loss of electrons

Question 8

reduction

Answer 8

loss of oxygen OR gain of electrons

Question 9

redox

Answer 9

a reaction in which both oxidation and reduction occur

Question 10

oxidising agent

Answer 10

causes another reactant to be oxidised and is reduced itself

Question 11

reducing agent

Answer 11

causes another reactant to be reduced and is oxidised itself

Question 12
